Features • Powered by NVIDIA® GeForceTM GTX 550 Ti Graphics Processing Unit (GPU) • Supports PCI Express 2.0 • Integrated with 1GB GDDR5 memory • Supports DirectX® 11 • Supports NVIDIA®SLI TM (Scalable Link Interface) technology (Note 1) • Supports 2 Dual-Link DVI-I and 1 mini HDMI connectors (Only GV-N550OC-1GI / GV-N550UD-1GI) • Supports 1 Dual-Link DVI-I,1 HDMI and 1 D-sub connectors (Only GV-N550WF2-1GI / GV-N550D5-1GI) • Supports HDCP (High-Bandwidth Digital Content Protection) technology 1.2. Minimum System Requirements • Hardware - 400-watt system power supply specification or above is recommended -Intel® Pentium® 4 or AMD AthlonTM XP class processor or higher -1GB system memory (4GB recommended) -Optical drive for software installation (CD-ROM or DVD-ROM drive) • Operating System -Windows® 7 -Windows® Vista -Windows® XP • SLITM Configuration If you are planning on using this graphics card as part of an SLI system, the following are required: -An SLI certified motherboard with two PCIe x16 slots and correct chipset driver -Two GV-N550WF2-1GI / GV-N550OC-1GI / GV-N550UD-1GI / GV-N550D5-1GI for SLI configuration; -A power supply with 650-watt or above is recommended -An SLI bridge connector (Note 1) SLI technology requires a PCI Express motherboard with two x16 physical connectors. Graphics cards working in an SLI configuration must be with the same model name (e.g. GV-N550WF2-1GI / GV-N550OC-1GI / GV-N550UD-1GI / GV-N550D5-1GI) and from the same vendor (e.g. GIGABYTE TECHNOLOGY). -7 - Introduction 2.

To protect them against damage from static electricity, you should follow some precautions whenever you work on your computer. 1. Turn off your computer and unplug power supply. 2. Use a grounded wrist strap before handling computer components. If you do not have one, touch both of your hands to a safely grounded object or to a metal object, such as the power supply case. 3. Place components on a grounded antistatic pad or on the bag that came with the components whenever the components are separated from the system. The card contains sensitive electric components, which can be easily damaged by static electricity, so the card should be left in its original packing until it is installed. Unpacking and installation should be done on a grounded anti-static mat. The operator should be wearing an anti-static wristband, grounded at the same point as the anti-static mat. Inspect the card carton for obvious damage. Shipping and handling may cause damage to your card. Be sure t...
